Your computer can have several "network interfaces". If you have two
network cards in the machine, then there will be a network interface
for each.

But your computer also has a "virtual" network card which listens to
the address 127.0.0.1 also known as localhost. This interface is
always present and is often used for TCP communication between
processes that live on the same machine.
